Initial operation and data processing on a system for real-time evaluation of Thomson scattering signals on the Large Helical Device
K. C. Hammond, F. M. Laggner, A. Diallo +11
A scalable system for real-time analysis of electron temperature and density based on signals from the Thomson scattering diagnostic, initially developed for and installed on the N…
Topology optimization of permanent magnets for stellarators
Caoxiang Zhu, Kenneth Hammond, Thomas Brown +5
We introduce a topology optimization method to design permanent magnets for advanced stellarators. Recent researches show that permanent magnets have great potentials to simplify s…
Designing stellarators using perpendicular permanent magnets
Caoxiang Zhu, Michael Zarnstorff, David Gates +1
We have developed a fast method to design perpendicular permanent magnets for simplifying stellarator coils based on existing codes. Coil complexity is one of the main challenges f…
Identification of important error fields in stellarators using Hessian matrix method
Caoxiang Zhu, David A. Gates, Stuart R. Hudson +4
Error fields are predominantly attributed to inevitable coil imperfections. Controlling error fields during coil fabrication and assembly is crucial for stellarators. Excessively t…
